VRRP, MSTP and multinetted server

Hi all.

I have two 3500yl. VRRP and MSTP will be activated on both of them. A trunk will be created between them and all the VLANs will be tag on that trunk.

On multinetted servers (two nics), if I plug one nic to a switch and the another nic to the second switch, will I still have the same performance of my network teaming on the server? Does this configuration enables a redundant access to this server?

Re: VRRP, MSTP and multinetted server

terminology:multinet is commonly used on divices using multiple subnets on the same (v)lan, not for multiple network adapters.

back to the question:most likely won't have the same performance!

when the NIC's are connected to the same switch you can configure this link as load balanncing etherchannel so both ports can be used simultanuously.if your you NIC's are teamed, and connected to different switches, the team is fault-tolerant only (failover)!only one NIC is active at a time for all traffic, no load balancing.

Re: VRRP, MSTP and multinetted server

Load balancing etherchannel must be done at both sides of the link.

from management and config guide page 12-27:>>>The two trunk group options (LACP and Trunk) use source-destination address pairs (SA/DA) for distributing outbound traffic over trunked links.SA/DA (source address/destination address) causes the switch to distributeoutbound traffic to the links within the trunk group on the basis of source/destination address pairs.<<<

If your server is Proliant, you can set the team config to "auto" (maybe other brands offer such option too).as the switch supports IEEE 802.3ad (LACP) and both nics are connected to the same switch, the team will form automatically.

I associate multihomed with multiple NIC's each in it's own subnet.A network team acts as a single NIC with a single subnet (unless you make it vlan-aware).
